如何排除 discord.py 中的角色

Question

所以我有一个紧急命令，以防万一，我必须对每个人进行 DM，但是机器人有问题，因为 DM 会导致错误（机器人的角色是 "BOTS"）

@bot.command(pass_context=True)
async def emergency(ctx, *, message: str):
    if admin in [role.id for role in ctx.message.author.roles]:
        for server_member in ctx.message.server.members:
            await bot.send_message(server_member, message)
    else:
        await bot.say("DENIED, You do not have permission to use this command")

和错误

Traceback (most recent call last):
  File "C:\Users\adamk\PycharmProjects\bot\venv\lib\site-packages\discord\ext\commands\bot.py", line 846, in process_commands
    yield from command.invoke(ctx)
  File "C:\Users\adamk\PycharmProjects\bot\venv\lib\site-packages\discord\ext\commands\core.py", line 374, in invoke
    yield from injected(*ctx.args, **ctx.kwargs)

在其他一些情况下您会收到此消息（您已被阻止，该用户已完全禁用 DM，等等），因此每次都捕获错误并继续更有意义它发生了。

@bot.command(pass_context=True)
async def emergency(ctx, *, message: str):
    if admin in [role.id for role in ctx.message.author.roles]:
        for server_member in ctx.message.server.members:
            try:
                await bot.send_message(server_member, message)
            except discord.Forbidden:
                pass
    else:
        await bot.say("DENIED, You do not have permission to use this command")

如果您还想检查角色，可以使用 discord.utils.get

if get(server_member.roles, name="BOTS"):
    # has role
else:
    # does not have role
